IP3 Receptor-2/ITPR2 Blocking Peptide (#BLP-CC116) is the original antigen used for immunization during Anti-IP3 Receptor-2 (ITPR2) Antibody (#ACC-116) generation. The blocking peptide binds and ‘blocks’ Anti-IP3 Receptor-2/ITPR2 primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.
